12 IS Lane Departure Warning Systems Published January 2007 Introduction Lane Departure Warning Systems (LDWS) are based on fundamental traffic rules. The main focus of LDWS is to help the driver keep the vehicle in the lane on highways and highway-like roads. Accordingly, a warning is issued to alert the driver in case of lane departure caused by, for example, inattention. LDWS are not intended to issue warnings with respect to collisions with other vehicles or control vehicle motions.

13 IS Lane Departure Warning Systems Scope This standardisation working draft specifies the definition of the system, classification, functions, human machine interface (HMI) and test methods for lane departure warning systems. These are in-vehicle systems that can warn the driver of a lane departure on highways and highway-like roads. The subject system, which may utilise optical, electromagnetic, GPS, or other sensor technologies, shall issue a warning consistent with the visible lane markings. The issuance of warnings at roadway sections having temporary or irregular lane markings such as road work zones is not within the scope. The standard shall apply to passenger cars, commercial vehicles and buses. The system will not take any automatic action to prevent possible lane departures. Responsibility for the safe operation of the vehicle remains with the driver.

16 PWI Forward Vehicle Collision Mitigation Systems Currently a Working Draft Introduction Forward Vehicle Collision Mitigation Systems (FVCMS) reduce the severity of collisions with forward vehicles that cannot be avoided, and may reduce the likelihood of colliding with forward vehicles. FVCMS require information about range to forward vehicles, motion of forward vehicles, motion of the subject vehicle, driver commands and driver actions. FVCMS detect vehicles ahead, determine if detected vehicles represent a hazardous condition, and warn the driver if a hazard exists. They estimate if the driver has an adequate opportunity to respond to the hazard. If there is inadequate time available for the driver to respond, and if appropriate criteria are met, FVCMS assess that a collision is imminent. Based upon this assessment, the FVCMS activate vehicle brakes to mitigate collision severity.

17 PWI Forward Vehicle Collision Mitigation Systems Scope This International Standard specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test methods for Forward Vehicle Collision Mitigation Systems (FVCMS). It specifies the behaviors that are required for FVCMS, and the system test criteria necessary to verify that a given implementation meets the requirements of this International Standard. Implementation choices are left to system designers, wherever possible. FVCMS mitigate rear-end collisions. By reducing the collision energy, FVCMS reduce the degree of property damage, personal injury, or the likelihood of fatality. They supplement crashworthiness systems such as airbags, seatbelts and other energyabsorbing systems by reducing the impact energy that must be isolated from the occupants.. By automatically activating collision mitigation braking after a collision warning occurs, FVCMS assist in slowing the vehicle when a collision is likely. While not required, this Standard permits collision avoidance to be attempted by a system that conforms to FVCMS. With the exceptions of single-track vehicles, and trucks with dual or triple trailers, the FVCMS are for use on road vehicles intended for public and non-public roadways. The systems are not intended for off-road use.
